ICD-10-PCS Table `BY3`
for Fetus and Obstetrical, Magnetic Resonance Imaging (MRI)

The ICD-10-PCS table below specifies all the valid combinations of the remaining characters beyond the first 3 characters (BY3) in the Imaging section, Fetus and Obstetrical body system, and Magnetic Resonance Imaging (MRI) root operation. Each row in the table specifies the valid combination of values for characters 4-7. The table contain only those combinations of values that result in a valid procedure code.
